Evaluating the Effectiveness of a Parent training Protocol Based on an Acceptance and Commitment Therapy Philosophy of Parenting
Thirty-four parents were referred by their CPS caseworkers to participate in one of two ACT for Parenting workshops. These workshops followed a 12 hour treatment protocol based on an acceptance and commitment therapy philosophy of parenting. Briefly, an ACT philosophy of parenting maintains that effective parenting requires awareness and acceptance of thoughts and feelings as they occur in the context of the parent-child relationship. An ACT philosophy of parenting also relies heavily on the identification and commitment to parenting values. Participants were asked to track acceptance and valuing behavior on a daily basis for 25 days prior to the intervention and 25 days post-intervention, as well as to complete a package of self-report instruments designed to measure both ACT specific and general psychological processes, at three different points (pre-, post- and follow-up). Nineteen parents received the treatment, and of those, seventeen provided follow-up data 3-4 months post-intervention. Results indicate statistically significant changes in the expected directions for scores on the BASC-2 Externalizing Composite as well as on the Meta-Valuing Measure. A total of 10 parents also evidenced clinically significant change in the expected directions on a variety of outcome measures

An Exploration of the Relationship between Worry and Other Verbal Phenomena
This study hypothesized a direct relationship among three verbal phenomena: derived relational responding, verbal intelligence, and worry. It also hypothesized that experiential avoidance would mediate the relationship between derived relational responding and worry. Overall, results from this study failed to support a relationship between worry and the other two verbal phenomena, however, results did support a relationship between derived relational responding and verbal intelligence. Additionally, results indicated a significant relationship between experiential avoidance and worry. Future research should clarify the relationship among the three primary variables of interest, improve measurement of these variables, be more sensitive to external validity, and promote the study of acceptance-based treatments that target experiential avoidance
College Dating Violence: Evaluating an Online Intervention
The purpose of this study will be to replicate and extend a randomized controlled trial that tested the effectiveness of an online bystander intervention educational program (STOP Dating Violence; O'Brien, Sauber, Kearney, Venaglia, & Lemay, 2019). Specifically, the intervention was modified and converted into an engaging animated video and then tested for its effectiveness. College students will be randomly assigned to one of three conditions: (1) the STOP intervention, (2) a website containing information about dating violence, and (3) a control condition. Data collection is currently underway. Preliminary data analyses (N=39) suggest that there is a difference in post test scores on the knowledge of bystander interventions measure across conditions (F(2, 36) = 3.876, p <; .03, η 2 = .18). This study will advance knowledge regarding how counseling psychologists might cost-effectively and successfully educate undergraduates about dating violence
Biologic Agents—A Panacea for Inflammatory Arthritis or Not?
Aim. To describe the retention rates for biological therapies in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS) in a clinical setting. Methods. All patients managed in a dedicated biological therapy clinic in a teaching hospital in Australia were assessed for continuation on biological treatments and reasons for switching to an alternative biological agent or cessation of treatment. Results. There was a lower retention rate for RA patients on biological therapies compared to PsA and AS patients and the retention rate for RA patients was lower than that reported in RCTs. Conclusions. The retention rate on biological therapies for RA patients was lower in the clinic setting than what is reported in RCTs. The reasons for the lower retention rate in the clinical setting are discussed but no clear determinants for nonresponse to biological agents were identifiable. These agents have very limited steroid sparing effects
Evidence for Nonlinear X-ray Variability from the Broad-line Radio Galaxy 3C 390.3
We present analysis of the light curve from the ROSAT HRI monitoring
observations of the broad-line radio galaxy 3C 390.3. Observed every three days
for about 9 months, this is the first well sampled X-ray light curve on these
time scales. The flares and quiescent periods in the light curve suggest that
the variability is nonlinear, and a statistical test yields a detection with >6
sigma confidence. The structure function has a steep slope ~0.7, while the
periodogram is much steeper with a slope ~2.6, with the difference partially
due to a linear trend in the data. The non-stationary character of the light
curve could be evidence that the variability power spectrum has not turned over
to low frequencies, or it could be an essential part of the nonlinear process.
Evidence for X-ray reprocessing suggests that the X-ray emission is not from
the compact radio jet, and the reduced variability before and after flares
suggests there cannot be two components contributing to the X-ray short term
variability. Thus, these results cannot be explained easily by simple models
for AGN variability, including shot noise which may be associated with flares
in disk-corona models or active regions on a rotating disk, because in those
models the events are independent and the variability is therefore linear. The
character of the variability is similar to that seen in Cygnus X-1, which has
been explained by a reservoir or self-organized criticality model. Inherently
nonlinear, this model can reproduce the reduced variability before and after
large flares and the steep PDS seen generally from AGN. The 3C 390.3 light
curve presented here is the first support for such models to explain AGN
variability on intermediate time scales from a few days to months.Comment: 10 pages using (AASTeX) aaspp4.sty and 3 Postscript figures.

Particle tracking in a salinity gradient: A method for measuring sinking rate of individual phytoplankton in the laboratory
This paper presents a new method to measure the sinking rates of individual phytoplankton “particles” (cells, chains, colonies, and aggregates) in the laboratory. Conventional particle tracking and high resolution video imaging were used to measure particle sinking rates and particle size. The stabilizing force of a very mild linear salinity gradient (1 ppt over 15 cm) prevented the formation of convection currents in the laboratory settling chamber. Whereas bulk settling methods such as SETCOL provide a single value of sinking rate for a population, this method allows the measurement of sinking rate and particle size for a large number of individual particles or phytoplankton within a population. The method has applications where sinking rates vary within a population, or where sinking rate-size relationships are important. Preliminary data from experiments with both laboratory and field samples of marine phytoplankton are presented here to illustrate the use of the technique, its applications, and limitations. Whereas this paper deals only with sinking phytoplankton, the method is equally valid for positively buoyant species, as well as nonbiological particles
X-ray Observations of the Broad-Line Radio Galaxy 3C 390.3
We present the data and preliminary analysis for a series of 90 ROSAT HRI and
two ASCA observations of the broad-line radio galaxy 3C 390.3. These data were
obtained during the period 1995 January 2 to 1995 October 6 as part of an
intensive multiwavelength monitoring campaign. The soft X-ray flux in the ROSAT
band varied by nearly a factor of four during the campaign, and the
well-resolved light-curve shows several distinct features. Several large
amplitude flares were observed, including one in which the flux increased by a
factor of about 3 in 12 days. Periods of reduced variability were also seen,
including one nearly 30 days long. While the HRI hardness ratio decreased
significantly, it is apparently consistent with that expected due to the
detector during the monitoring period.
The two ASCA observations were made on 1995 January 15 and 1995 May 5. The
0.5-10.0 keV spectra can be adequately described by an absorbed power-law.
There is no evidence for a soft excess in the ASCA spectra, indicating that the
ROSAT HRI is sampling variability of the X-ray power-law. A broad iron line was
observed in a longer 1993 ASCA observation, and while there is statistical
evidence that the line is present in the 1995 spectra, it could not be resolved
clearly. There is evidence, significant at >90% confidence, that the photon
index changed from 1.7 to 1.82 while the flux increased by 63%. The spectral
change can be detected in the spectra below 5 keV, indicating that the origin
cannot be a change in ratio of reflected to power-law flux. A compilation of
results from ASCA and Ginga observations show that on long time scales the
intrinsic photon index is correlated with the flux.Comment: 17 pages using (AASTeX) aaspp4.sty and 4 Postscript figures.

Influences on the food choices and physical activity behaviours of overweight and obese pregnant women: A qualitative stud
Objective: to qualitatively explore influences identified by overweight/obese pregnant women on food choices and physical activity (PA) behaviours; to determine the impact of pregnancy on these factors; and to inform development of future lifestyle interventions during pregnancy. Design: cross-sectional interview study. Setting: maternity hospital, Ireland. Participants: pregnant women (n=22), early pregnancy Body Mass Index > 25 kg/m2. Measures: barriers to and facilitators of healthy eating and PA in overweight/obese pregnancy. Interviews were transcribed verbatim and analysed using inductive thematic analysis. Findings: overweight/obese women perceived the following factors to influence their food choices and PA behaviours: personal (e.g. age, enjoyment, health, aesthetic appearance, and response to fatigue); social (e.g. social support, food modelling, social facilitation and weight bias) and environmental (e.g. food salience and the obesogenic environment). These factors affected PA and food choice trajectories differently according to socio-economic and socio-cultural context. Conclusion and Implications: personal, social and environmental factors affect food choices and PA behaviours. Pregnancy is a powerful stimulus for positive changes in food choices particularly. This change is driven by desire for healthy pregnancy outcome, and is not intrinsically motivated. Healthy lifestyle interventions should aim to sustain positive changes beyond pregnancy through: empowerment, intrinsic motivation, family-centred approach, and behavioural goals
